CAgTTLE-STANCHION.

Specification of Letters Patent.

Patented March 12, 1907.

Application filed November 26, 1906. Serial No. 345,162.

.To all whom it may concern.-

Be it known that I, Jol-IN HACKER, a citizen of the United States,residing at Caledonia, in the county of Kent and State of Michigan, haveinvented a new and useful Cattle-Stanchion, of which the following is aspecification.

This invention has relation to cattlestanchions, and it consists in thenovel construction and arrangement of its parts, as hereinafter shownand described.

The object of the invention is to provide a stanchion of the usualpivoted type, one side of the stanchion being fixed with relation to thehead and foot pieces thereof, while the opposite side is jointed and isadapted to swell or bow laterally with relation to the head and footpieces. Means is provided for holding the last said side in bowedrelation to the opposite side, so that the animal may insert its headand neck between the sides, and in so doing the neck comes in contactwith a slidable sleeve and moves the same, so that the members of thebowed side may swing into vertical alinement, when the said sleeve willJfall over the joint connection between the members and render themrigid. In this manner the animal itself closes the stani chion and thesame does not require manual operation to secure the animal.

In the accompanying drawings, Figure l is a side elevation of thestanchion with parts in section. Fig. 2 is a detailed enlarged sideelevation of a sirle rod and member, showing the sleeve in section.

The stanchion comprises the head-piece 1 and the foot-piece 2, each ofwhich is provided with a suitable trunnion 3. The head-piece l may beprovided with an upward extension, as shown, if necessary, to preventthe stanchion from describing a complete rotation. The relatively liXedside piece 4 rigidly connects the head-pieces 1. and 2 together. Theside member 5 is pivoted at the point 5 to the end of the head-piece l,and the sleeve 6 is slidably mounted upon the member 5. The rod 7 ispivoted near its upper end to the lower end of the member 5. The upperend of the said rod 7 is provided with a notch 8, which is adapted Vtoreceive a portion or' the lower end of the sleeve 6. The upper end ofthe tube 9 is attached to the lower end of the rod 7. Said tube isprovided in its sides with-the elongated openings 10 10.' The rod 11 ispivoted at the point 11 to the end of the foot-piece2 and enters thelower end of the tube 9. Said rod 11 is provided with a cross-pin l2,which enters and operates within the elongated openings l0 10. 'Iheparts from 5 to 12, inclusive, constitute a laterally-expandible orbowable side of the stanchion, and in order to bowjthe said parts andhold them in such position the sleeve 6 is slipped up along the upperportion of the member 5. The said member is then swung on its pivot sothat a bow is termed between the said member and the rod 7 and itsconnections. Ihus the upper end of the rod 7 is swung out of verticalalinement with the member 5 and the lower edge ol the sleeve 6 ispermitted t0 fall into the notch 8, and the parts are thus held in bowedrelation. The pin l2, operating in the slots 10, limits the upwardmovement of the tube 9. When the parts are in the position last abovedescribed, the animal (not shown) thrusts his head and neck through thesides of the stanchion. Itsneck comes in contact with the sleeve 6 andthe same is pushed up along the member 5. 'Ihus the lower edge of thesleeve is disengaged from the notch S of the rod 7, and by gravity thesaid rod 7 will swing into vertical alinement with the member 5, and thesleeve 6 will drop down over the pivotal connection between the said rod7 and member 5 and hold the same in rigid relation. Thus the parts ofthe pivoted sides of the stanchion are brought into vertical alinementand substantially parallel with the side 4', and the animal 1s securedin the fixture. V

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

1.. A stanchion comprising head and foot pieces with a side piecerigidly connecting the same together, an opposite side piece composed ofpivoted sections which in turn are pivotally connected with the head andfoot pieces and a slidable member coperating with the end oli' one ofthe sections for holding said section of the last said side piece mlaterally-extended position and adapted to be moved by the animal torelease the side sections whereby they may assume substantially verticalpositions and be held in such position by said sliding member.

2. A stanchion comprising head and foot pieces, a side piece rigidlyconnecting the head and foot pieces together, a laterallymovable sidecomprising a member pivoted to the head-piece, a sleeve slidably located"I IO In testimony that I claim theforegoing as my own I have heretoaihxed my signaio ture in the presence of tWo Witnesses.
